2 years later: 2 years of running WordPress and MySQL on Docker in a VPS

It’s been 2 years since I migrated this site from a native install on a VPS to another VPS running Docker. I covered my migration in a number of posts, the first of which is here:

The surprising thing (maybe? maybe not?) is that the site has been up and running for the past 2 years with no issues. I think I rebooted the VPS a couple of times for reasons I can’t remember, but other than that the site’s been up reliably for the past 2 years.

It’s also been 2 years since I last renewed my SSL certificate, so time to do a couple of updates. More to come later.

Weblogic 12c (12.1.3) Datasource for MySQL 8.0.15 getting error: Unable to load authentication plugin ‘caching_sha2_password’

When creating a new Datasource on Weblogic 12.1.3 to MySQL 8.0.15, I got this error:

Unable to load authentication plugin 'caching_sha2_password'.

A quick search found this question, and the solution is to switch the password encryption back to the approach used in prior MySQL versions with:

ALTER USER 'youruserid'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';

Exporting select result from MySQL and getting the error ‘ERROR 1290 (HY000): The MySQL server is running with the –secure-file-priv option’

To use ‘select … into outfile’ on MySQL the user needs to have the FILE permission as described here.

Even with this privilege however, if there server is running with the –secure-file-priv option you’ll see this error:

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option

When this option is enabled there’s usually one or more paths by default that are configured that you can import and export to. You can find these paths using:

mysql> SHOW VARIABLES LIKE "secure_file_priv";


| Variable_name    | Value                 |


| secure_file_priv | /var/lib/mysql-files/ |


1 row in set (0.02 sec)

Knowing where our trusted location is for importing/exporting, lets try again:

select examplecol from exampletable 
order by createdate desc limit 1 
into outfile '/var/lib/mysql-files/mysqlout.txt';


This is discussed in answer to this question here.
